Hybrid_From_Hell Posted October 5, 2009 Share Posted October 5, 2009 Had a muppet someone round tonight saying 90 handled awfull, went out with him and I had to agree, that was whilst trying not to puke within the said 90 flaying all over the road F knows what lift is on it, but it handles like a drunk pig on rollerblades, and told him as much however look as I might I am stumped as to what lift it acually has So, me question to the forum is simple, where you have a 1 2 3 4 5 inch lift, what eaxctly is the measurement over "standard" where is it taken from, and more importantly WTF is it as well so I can work it out ? Yours green and trying to keep din dins in Nige Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted October 5, 2009 Share Posted October 5, 2009 I would assume the safest measurement would be from top to bottom spring seat? Quote Link to comment Share on other sites More sharing options...
TSD Posted October 5, 2009 Share Posted October 5, 2009 The only 'offical' published figures I've seen are in the WSM for a 110 with Boge SLD, where the test for suspension height is for the gap between bump stop and axle pad on the rear axle to be in excess of 67mm in running trim.

ejparrott Posted October 6, 2009 Share Posted October 6, 2009 the spring in its free state? Does it need an anti-roll bar fitting then? Possibly not had castor corrected balls too... Quote Link to comment Share on other sites More sharing options...
Aragorn Posted October 6, 2009 Share Posted October 6, 2009 I would guess measuring between spring platforms would be the best way. The stock measurement was floating around on here, as i've used it for spring rate calculations before, but iirc it was around 8-9" on the front. Perhaps someone else can confirm that though.

Pete Attryde Posted October 6, 2009 Share Posted October 6, 2009 I have always gone with the info in Trev's spring calc :- I've yet to get authorative 'standard height' compressed lengths but 10-10.5 inches front and 11-12 inches rear is the best estimate I've got so far Pete.

HTH Dave I 'think' the figure I worked with was 75mm - it is on the board in the workshop so I'll check.... Anyway, I measured it off my parents' standard 110 CSW which seems to sit at a nice standard looking height. Quote Link to comment Share on other sites More sharing options...
Aragorn Posted October 6, 2009 Share Posted October 6, 2009 I've yet to get authorative 'standard height' compressed lengths but 10-10.5 inches front and 11-12 inches rear is the best estimate I've got so far 10" compressed length on a 15" 175lb spring means theres about 875lb on each front spring, giving a front axle weight of 795kgs (plus any unsprung weight, ie the axle etc) which doesnt sound tooo far from stock?

nicks90 Posted October 6, 2009 Share Posted October 6, 2009 i was told 10" front and 11" rear for a standard 90 tdi using standard non saggy genuine springs when i asked the same question of my local landy specialist many moons ago. Thats certainly what i have based all my calcs on when changing springs on my 90. Quote Link to comment Share on other sites More sharing options...
gwyn lewis Posted October 6, 2009 Share Posted October 6, 2009 The best way to measere your lift is to measure your spring hights with the vehicle parked on level ground,measure from top to botom of the rear of the front spring,and the same for the rear spring,with quality springs you will find that the drivers side is always slightly taller STD 90/110 FRONT SPRING measures 260mm +/- 5 mm The REAR SPRING should be around 300 mm +/- 10mm STD Disco/RRc FRONT SPRING measures 250 mm +/- 5 mm The REAR SPRING should be around 300 mm +/- 10mm These measurments are what i have taken over the years to calculate what lift you have got or havent got From the standard measurments you can calculate what lift you have got Hope this will help what you need GWYN LEWIS Quote Link to comment Share on other sites More sharing options...

gasket Posted October 8, 2009 Share Posted October 8, 2009 sorry if this is a stupid question, but once you have identified 'if' and 'how high'. What are you going to do to fix the handling? Cause i have a 2" lift on my 90 and it drives fine (as can be expected) no problems motorway, a-roads, off road and 2" seems standard for a lift. So they will drive no probs with 'a lift', is knowing the lift hight the issue, or could it be more wheel balancing, offset, play in the steering, steering box on its way out, track rods etc? just food for thought.

Aragorn Posted October 8, 2009 Share Posted October 8, 2009 Well at least now he can measure it and see if it IS a 2" lift or if its something larger and sillier... Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted October 8, 2009 Share Posted October 8, 2009 STD 90/110 FRONT SPRING measures 260mm +/- 5 mm The REAR SPRING should be around 300 mm +/- 10mm This matches my (standard non-lifted) 90 pretty much exactly. I have 300mm nearside and 310mm offside on the rear and 240mm nearside and 260mm offside on the front. Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted October 8, 2009 Author Share Posted October 8, 2009 Erm, 4.25 ins to be precise Heap Told matey to remove the lift kit spring blocks and have given him a set of sh spring to fit which he is doing this weekend, has sold the silly too big tyres too, and has bought some insa turbos frankly for the money he paid for it, it could be decent, a chav has been at it and I knew it was too high but until gwyn came along with the measurements didn't know how high, I have also plasmad off the abortion that was a front winch bumper and done a host of welding to it but it could do prob next year with a full cross member, but a 300 tdi for £2750 is cheap methinks, the roof rear door don't match rest of 90, colour wise (guessing prang) but he's going to TC it anyways Ta for the help Nige Quote Link to comment Share on other sites More sharing options...

Ex Member Posted October 9, 2009 Share Posted October 9, 2009 STD 90/110 FRONT SPRING measures 260mm +/- 5 mm The REAR SPRING should be around 300 mm +/- 10mm STD Disco/RRc FRONT SPRING measures 250 mm +/- 5 mm The REAR SPRING should be around 300 mm +/- 10mm I had 250/310 on the 90 stock and 220/280 on my Disco. I always thought stock Discos were an inch or so lower than Defenders. Quote Link to comment Share on other sites More sharing options...
